Figures REF  and REF  show the property charts for \(Pe=0.01\)  and \(0.02\) , respectively, using the Lax-Wendroff method for Lele's sixth order compact scheme [1]} for a structured uniform grid. One notes striking similarities in the properties between the present uniform grid and the lesser stretched non-uniform grid results for \(\gamma =1.5\)  case using NUC6. This demonstrates that benefits of the developed Lax-Wendroff method with the non-uniform compact scheme is retained for the special case of the uniform grid. In Fig. REF , one notices that increasing the Peclet number from \(Pe = 0.01\)  to \(0.02\) , increases the admissible \(N_c\)  value, both with respect to \(|G_{num}|/|G_{phys}|\)  and \(\alpha _{num}/\alpha \) . For the uniform grid, one again notes the extended vertical range of the \(|G_{num}|/|G_{phys}| = 1\)  contour that gives a higher value of \((kh)_{max}\) , i.e. higher resolution. In Fig. REF , one notices the dispersion properties to be quite similar to those shown in Fig. REF  for the NUC6 compact scheme using the non-uniform tangent hyperbolic grid.
